+By default, the visualization generated by `clusterctl describe cluster` hides details for the sake
 of simplicity and shortness. However, if required, the user can ask for showing all the detail:
 
 By using the `--disable-grouping` flag, the user can force the visualization to show all the machines
 on separated lines, no matter if they have the same state or not:

 It is also possible to force the visualization to show all the conditions for an object (instead of showing
 only the ready condition). e.g. with `--show-conditions KubeadmControlPlane` you get:
